VFX1 connectors and pinout

The aim for this document is to make available VFX1 technical information, that might help in developing ( linkboxes or support for tracking) and/or repairing VFX1s.

We have the following connectors in the system

• The VESA feature connector, present in the VIP card that interfaces to a video card.

• The VGA connector, of interest if you are doing video linkboxes

• The connector in the helmet, that goes to the vIP card, where video and tracking signals are transferred.

VESA feature connector ( in VIP card)

A 26 pin ( 2 rows of 13) standart connector, designed by an idiot who did not think about preventing it from being connected the wrong way. When you connect it the wrong way some chips in the VIP card are destroyed.

And I assume that pins 1 - 12 are outputs, and 17 - 19 are inputs. Is this correct?

The reason is this - I have a Rombo Media Pro+ video digitising card. It chroma keys its output into the vga monitor signal. However, although it is supposed to work with an ET-4000 with Hi-colour RAMDAC, the colours on screen behave as if the top 2 bits of colour information are missing, and red, green, blue signals are swapped around. Rombo has suggested that this may be due to insufficient buffering on the feature connector outputs, and is happy to sell me a buffer device for 50 pounds. I would rather save about 45 pounds, and build my own. I assume it would require (for example) a 74F244 buffer IC (or two).

Can anyone help? Any information on the feature connector would be highly appreciated!

AMC

ATI has used a connector called AMC in some of their cards. It seems that the AMC is just an "extended normal VGA feature connector", as far as the pinout is concerned.

ATI Technical Support feature connector info: The 26 pin BERG connector on ATI products is KEYED with pin Z13 missing and should be labelled as follows:

------------------------------------------------------------ -----

IBM defines the feature connector in the following manner:

Pin Name Description

Y1 C0 Colour BIT 0: an output when 'Select Internal Video' is hi.

Y2 C1 Colour BIT 1: an output when 'Select Internal Video' is hi.

Y3 C2 Colour BIT 2: an output when 'Select Internal Video' is hi.

Y4 C3 Colour BIT 3: an output when 'Select Internal Video' is hi.

Y5 C4 Colour BIT 4: an output when 'Select Internal Video' is hi.

Y6 C5 Colour BIT 5: an output when 'Select Internal Video' is hi.

Y7 C6 Colour BIT 6: an output when 'Select Internal Video' is hi.

Y8 C7 Colour BIT 7: an output when 'Select Internal Video' is hi.

Y9 DAC Clock Video clock for adapter palette/DAC. Output when

'Select Internal DAC Clock' is high.

Y10 DAC Blanking Blanking Signal for adapter palette/DAC. Output when 'Select

Internal Syncs' is high.

Y11 Ext. H Sync Output when 'Select Internal Syncs' is high.

Y12 Ext. V Sync Output when 'Select Internal Syncs' is high.

Y13, Z1, Z2, Z3, Z8, Z9, Z10 & Z11 Ground

Z4 Select Internal Defines colour pins (C7 to C0) as outputs when high.

(Video) The adapter pulls this signal to +5 volts through a 4.7K ohm resistor.

Z5 Defines SYNCS and blanking pins as outputs. The adapter uses 4.7K ohm

pull-up resistor.

Z6 Defines the DAC Clock pin as an output.

Z7, Z12 & Z13 Not used

It is a HD26 female + male connector

VFX1 Helmet Connector

This is what I worked out the VFX1 pinout to be.

I think most of it is correct. Rob

• Electrical/mechanical description and part number

The description of the connector is here:

 

| |I2C Connector |

This document describes the I2C Bus connector used on many of our products.

Many of our customers have been asking us about the I2C Bus connector we use on many of products. These customers want to design this connector into their systems. This document describes this connector and provides information on its pinout and source.

MCC offers a variety of I2C based products. These products include our I2C Bus Monitor, iPort RS-232 to I2C Host Adapter, and iPack I2C Bus Cards. To provide a standard way to connect these products, we use the Molex SEMCONNTM ACCESS.bus Connector (Part# 15-83-0064). This high quality locking connector was originally specified for use in ACCESS.bus based systems. It includes four (4) lines used for I2C Clock (SCL) and I2C Data (SDA), Ground (GND), and +5 VDC. The +5VDC line is not required for I2C, but provides an optional way to power attached I2C devices.
